NEET BIOLOGY

Detailed explanation-1: -Carbon dioxide is a waste product of aerobic respiration in plant cells.

Detailed explanation-2: -Some of the oxygen produced in the process of photosynthesis is used in respiration by the leaf cells but the major portion of it is not required and it diffuses out into the atmosphere through the stomata. Therefore, it may be called a waste product of photosynthesis.

Detailed explanation-3: -During oxidation, the oxygen combines with the food we eat, liberating energy and waste products (carbon dioxide and water). This process is called cellular respiration.

Detailed explanation-4: -Plants need to excrete excess carbon dioxide and oxygen. Carbon dioxide is a waste product of aerobic respiration in plant cells. Oxygen is a waste product of photosynthesis.

Detailed explanation-5: -The waste product of photosynthesis is oxygen gas, O2. The chemical reaction of photosynthesis can be stated as follows: Carbon dioxide and water use the sun’s energy to undergo a chemical reaction in which glucose is created and oxygen is given off as a waste product.
